Why Does My Cat Need Yearly Exams?

Millions of cats die every year from diseases that keeping them indoors can not protect them against. Cats are very good at hiding illness and typically do not show signs until it is too late to treat the disease. However many of these diseases can be caught early (prior to any clinical symptoms) with bloodwork and physical exam and treated successfully.

Real examples from the Animal Health Clinic
of cases that a physical exam helped save a cat's life


RosieRosie is a sweet 5 month old kitten who we were seeing for the first time. She was eating normal but had been vomiting off and on for a week and was not growing as fast as expected. She was acting like a normal happy kitten throughout most of these vomiting episodes. On exam the veterinarian felt her intestines were firmer than normal, we did x-rays, and decided to do an exploratory surgery. In surgery the vet saw there was at least 1 foot of small intestine that was abnormal and needed to be removed. This abnormal part of the intestines was not allowing Rosie to absorb the nutrients she needed to grow and thrive. After surgery Rosie was eating the next day and no vomiting. She healed wonderfully and is now a 2 & ½ year old cat that spends her days playing with her brother and sister at home. If Rosie’s owner did not bring her in to get examined she could have easily thought the vomiting was a normal thing that some cats do and we may not have been able to save her in time.
Curly Sue is a beautiful light orange kitty who we began seeing here with her 2 brothers when she was only a few weeks old.

At her 1 year vaccine appointment she was acting perfectly normal at home but the vet noticed her gums were a little paler than expected. We did bloodwork and discovered she had an immune mediated disease attacking her red blood cells. Curly Sue was put on medication, has needed follow up bloodwork and exams to make sure she was responding to the medications and is currently thriving and doing wonderful at home. This was a condition that if not found and treated quickly could have been fatal.

Chantel Chantel is a senior kitty who came to see us for her senior exam.

The examination showed she had dental disease and was overweight but was acting normal at home. The vet recommended we do senior bloodwork and it was found that Chantel had early diabetes. Since it was caught early before she showed any signs we tried to just change her food to a prescription food made for diabetics. We rechecked bloodwork and it was better, so her diabetes was caught early enough that she did not need insulin injections.

Molly Molly is a senior kitty who presented to us for his senior exam in 2012. The examination in 2012 did not show any abnormal findings and she was acting normal at home. We did routine senior bloodwork and found Molly had early hyperthyroidism. It was recommended that she start medication for hyperthyroidism but the owner chose not to start medication at that time. We saw Molly again for her senior exam in 2013 and she had a new heart murmur and had lost 6 lbs. We again did senior bloodwork and the thyroid level had increased even more. Molly’s hyperthyroidism was damaging her other organs (especially her heart) and causing her to lose an unhealthy amount of weight. We started her on a new food that is specially made to treat hyperthyroidism in cats. Molly’s thyroid disease is currently well regulated and she is doing wonderful. Molly’s disease was going to be fatal , but a simple food change and monitoring her through bloodwork and physical exams saved her life.
